The Labour Party (Greenlandic: Sulissartut Partiat) was a short-lived leftist political party in Greenland. The party was founded in early 1979 as the political wing of the Sulinermik Inuussutissarsiuteqartut Kattuffiat (SIK) trade union centre.[1][2] SIK had previously supported Siumut, but that cooperation had been terminated in the fall of 1978.[1]

Sulissartut was closely aligned to Siumut in major political issues.[3] Also, Sulissartut supported Siumut in elections to the European Parliament.[1]
